How do you track the amount to use for required minimum distributions,

[John A]

In your daily recordkeeping system, how do you track accrued contributions for individuals for purposes of determining the balance to use for required minimum distributions? Would your system automatically add a contribution made on September 1, 2000 for 1999 to the 12/31/99 balance to show you the amount to use for a year 2000 required minimum distribution?
